Title: System permitting the adjustment of quartz watches "without pushbuttons outside the case"
IPC: G04B19/18
Filed: 1982-12-02
Abstract: Device permitting the adjustment of quartz watches by pressure on the glass. The invention relates to the cases of quartz watches provided with a contact adjustment system. The invention permits the adjustment of these watches by pressure at various points of the glass without recourse to pushbuttons outside the case. It is composed of a case 9, of a ring for holding the module 8, of a dial 3 equipped with small spindles 5 which will act as pushbuttons, of a glass 2, of a very flexible joint 6 which holds the dial 3 and the glass 2 inside the ring 14. When pressure is applied on a corner of the glass 2, the flexible joint 6 is crushed and the spindle 5 then establishes the desired contact on the circuit 10. The most advantageous application relates to liquid crystal watches with one to four contacts regardless of the shape of the glass, even if it is necessary to have recourse to simultaneous pressure on two contacts.

Patent FR-2564646-A1 (FR)
Inventor: BILLARDON MICHEL
IPC: H01S3/09
Filed: 1984-05-21
Abstract: The invention envisages control devices acting on the laser to vary in time the electron/photon interaction, means proceeding to a State I in which they alter the optimal conditions for laser amplification; and a State II in which that reestablish said optimal conditions, which control devices permit the improvement of the peak amplitude and stability of the laser pulses and the rate and stability of the pulse period. According to another aspect of this invention, the two states are alternated, preferably periodically or almost periodically. The duration of State I should be selected by comparison with the characteristics of the electron packet and, in particular of the relaxation time observed for said packet. If the duration of State II is set to a value to be comparable to or longer than the electron relaxation time, the peak amplitude of the laser pulses is increased. The duration of State II should be selected by comparison with the natural macropulse width. If the duration of the State II is set to a value shorter than the natural duration of the laser macropulses, the repetition rate of the laser pulses can be increased.
